[gentoo-user] Rx Errors on NIC

[Drew Tomlinson]

I have a AMD Athlon 2800+ processor running on a Asus A7N8X Deluxe 
motherboard.  This motherboard uses the Nvidia NForce2 chipset.  It has 
both an Nvidia and a 3Com 100 mbps network adapter integrated.

Initially I used the Nvidia network adapter but noticed a lot of Rx 
errors.  The "errors" and the "frame errors" matched exactly.  I did the 
standard testing to try and isolate the problem.  I tried known working 
patch cables and known working hub ports.  Then when the errors 
persisted, I even moved the box to a known working cable run.  The 
errors remained.

So I figured that the actual port on the motherboard must be bad.  I 
recompiled my kernel with 3Com networking support and began using the 
3Com port but I am still getting errors.  Here's my current 'ifconfig' 
output:

eth2      Link encap:Ethernet  HWaddr 00:26:54:0C:60:8D 
          inet addr:192.168.1.6  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST NOTRAILERS RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:131785 errors:481 dropped:0 overruns:0 frame:760
          TX packets:168955 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:27189676 (25.9 Mb)  TX bytes:169280962 (161.4 Mb)
          Interrupt:18 Base address:0xb000

The errors have changed a little in that now the "frame errors" exceed 
the "errors".  How can that be?  I must not understand the output.  
Anyway, I'm starting to think I may have some configuration issues as I 
find it hard to believe that both ports are bad.  I'm a Gentoo newbie 
and started with kernel 2.11.  I've upgraded once to 2.13-r5 which is 
where I'm at now.  I have not changed any networking parameter from 
their defaults as far as I recall.  Any ideas on what might be going on?

Thanks,

Drew
